What is Bitcoin Stock-to-Flow (S2F)?

As interest in Bitcoin has grown, many models and metrics have emerged to analyze its value and predict future price movement. One model that has caught the attention of crypto investors is Bitcoin Stock-to-Flow (S2F). This tool is based on the estimation of the potential value of the asset, taking into account the speed of new bitcoins entering the market and the number of coins not yet mined. In this article, we will find out the origin of the S2F model and learn how it works.

Introduction to Bitcoin Stock-to-Flow

Stock-to-Flow (S2F) is a model that estimates the value of Bitcoin based on the ratio between its total "stock" (the existing number of coins) and "flow" (new coins entering the market as a result of mining). The idea behind S2F is that due to Bitcoin's limited issuance, its price will inevitably increase.

The S2F model is based on two concepts:

Who created the Bitcoin Stock-to-Flow model?

The Bitcoin Stock-to-Flow model became widely known due to an anonymous analyst known by the nickname "PlanB". This analyst published the model in March 2019 in an article on Medium titled "Modeling Bitcoin's Value with Scarcity".

Can Bitcoin S2F be trusted?

Our team doesn’t recommend relying solely on the signals of the Bitcoin Stock-To-Flow model to make Bitcoin rate predictions. The history of S2F shows that this model doesn’t always accurately predict Bitcoin’s price.

For example, in the fall of 2021, PlanB assumed that Bitcoin would reach the $100,000 mark by the end of the year. However, in reality, the cryptocurrency's rate slowed its growth and stopped at $68,789 on November 10. When forming an individual investment strategy, we recommend that you combine several different metrics and analytics.

Always do a DYOR (do your own research). You can read our article about proper DYOR on the EXBI blog.
